SPECIFICATIOIiforming part of Letters Patent No. 721,806, dated March 3, 1903.

To all whomit nay concern:

Be it known that I, JOSEPH H. JAMES, a citi-" zen of the United States of America, residing at Fort Scott, in the county of Bourbon and State of Kansas, have invented certain new and useful Improvements in Display-Racks, of which the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, forming a part hereof.

This inventionhas special reference to racks for displaying merchandise in showwindows and it consists in certain novel features of construction, as will be hereinafter first fully described and then particularly pointed out in the claims.

. The annexed drawing represents a display-- rack embodying my improvements, partly in section and partly in elevation.

In carrying out my invention I form below the floor A of the show-window a supportingframe B, consisting of vertical posts or stand: ards C and horizontal beams D, secured to and supported by the said posts or standards.

' Extending between and seen red rigidly in the the runways F, so as floor of the show-window and the uppermost beam D is a stationary tube or hub E, having annular grooves or runways F formed in its ends. Inserted through this hub or tube is 'a hollow shaft G, having adjustable cones II, which are adapted to be turned up against to secure the shaft within the hub or tube, antifrictiomballs being inserted between the runways and the cones to permit the shaft to turn easily on or in the hub. \Vithin the shaft G is a second shaft- I, and within the shaft I is another shaft J, the several shafts having pulleys K L M secured to their lower ends. Additional shafts or fewer shafts may be employed at pleasure, the exact nu her being immaterial, as will be readily un erstood. The upper ends of the shafts G and I are formed with runways G I, in which antifriction-balls are fitted, and adjustable cones I J on the shafts I J, respectively, are adapted to be turned down against these runways, so that each shaft is hung or supported on the upper end of the next outer shaft. Corresponding adjustable suitable motor. device the pulleys R S T are of equal diames tors; but the A iplication filed December 13,1902. SeriaiNo.135,0s9. on model.)

cones are provided near the lower ends of the shafts to coact with runways'in the beams!) to hold the lower portions of the shafts steady, and thereby prevent vibration of the same. Upon the upper portions of the shafts G I J are secured. shelves or disks N O P, upon which are placed the articles of merchandise to be displayed; The pulleys K L M on the lower ends of the shafts are connected by suitable belts with pulleys R S T, respectively secured on a counter-shaft Q, which is mounted in suitable bearings in the floor of the show-window and the bottom of the frame B and is' provided with a driving-pulley U, to which power is applied from any In the preferred form of the pulleys K L M are of different diameters, so that the shafts towhich they are attached and the shelves carried by the shafts may be rotated at different speeds, and some of the connecting-belts may be crossed, if so desired, so that the shelves will move in opposite directions.

It will be readily seen that I have provided a very simple rack by which merchandise may be displayed in a show-window and by being constantly rotated will attract the attention of passers-by. The several shafts are firmly supported against vibration and at the same time are permitted to run easily and without noise.

Having thus described my nvention, what I claim, and desire to secure by Letters Patent, is-
